Description
Technical field
The present invention relates to aircraft fire protection fields, the more particularly, to extinguishing device and system of aircraft cabin.
Background technique
As the demand of the raising of New Large Aeroplane cabin useful load, passenger constantly changes and the continuous hair of logistic industry
Exhibition, the interior cargo stored of aircraft hold become to become increasingly complex.The cargo of the needs such as the lithium battery of large-scale use storage,
So that the cargo in aircraft cabin has more unsafe incendiary sources, this adds somewhat to the risk of fire in aircraft cabin
And risk.
Cargo hold fire extinguishing system is one of important leverage means of airplane in transportation category flight safety.Existing Typical Aircraft cargo hold
Fire extinguishing system generally includes the fire-suppression bottle and fairly large whole fire extinguishing pipe network or pipeline of large capacity.In such existing scheme
In, extinguishing chemical is stored in the large capacity fire-suppression bottle of inert gas pressurization.When executing fire extinguishing program, extinguishing chemical is distributed by pipeline
And transportation system reaches specified flame range, is sprayed by fighting nozzle, realizes and inhibits to the fire behavior of target area.
In such existing scheme, fire-fighting pipeline conveying and the design of distribution system, are entire fire extinguishing system design works
Important link.Especially in the design of bulk transport class aircraft fire suppression system, fire-fighting pipeline design can become extremely complex, manage
Road arrangement need to consider and the spacing of other systems and aircraft main structure, extinguishing chemical flow resistance, the pressure-resistant limit of material, pipeline
The factors such as assignment of traffic.
One problem of fire-fighting pipeline bring of bulky complex is, the weight indicator or ratio of the fire extinguishing system occupied
Can be higher, cause the waste in space and resource on machine.For example, by taking 168 grade airplane in transportation category of certain type as an example, fire-fighting pipeline system
Weight be about 5kg, account for the 10% of fire extinguishing system total weight.FAA (US Federal Aviation Administration) has promulgated that consulting is logical in 2008
AC25.795 is accused, according to the Advisory Circulars suggestion, fire-fighting pipeline design should meet corresponding requirement of shelter, and the requirement is further
Increase the complexity of fire extinguishing system circuit design.
Another problem is that the pressure loss of the fire-fighting pipeline of bulky complex during extinguishing chemical discharges is more aobvious
It writes, the cost efficiency of fire extinguishing system is bad, and circuit design, installation, maintenance are complex.And in order to enable circuit design not excessively
Complexity needs the fire-suppression bottle using large capacity, is generally had to thus using spherical or spheroid shape bottle body, and this bottle body for
It is complex for installing and arrange on the machine of fire-suppression bottle, it correspondingly will increase installation maintenance cost.
In addition, the other problems of existing aircraft hold fire extinguishing system further include the pipeline of bulky complex, it may be because of pipeline group
Part includes the failure of various application valve bodies, and makes fire extinguishing system locally even global failure, and security risk is larger, fire extinguishing system
Global reliability is not high enough.
Therefore, it is urgent to provide a kind of new extinguishing devices and system for aircraft cabin, to eliminate existing aircraft cargo bay
The drawbacks described above of fire extinguishing system.
Summary of the invention
The technical problem to be solved by the present invention is in order to overcome pipeline needed for existing aircraft hold fire extinguishing system huge multiple
It is miscellaneous, thus install, maintenance cost it is higher, the not high enough defect of the safety of fire extinguishing system, reliability proposes a kind of new be used for
The extinguishing device and system of aircraft cabin.
